Using Python‑Jenkins API to Manage Jenkins Jobs and Views

Background: the need to trigger Jenkins builds from backend code leads to using the python‑jenkins library, which provides a Python wrapper for Jenkins API operations.

Installation: sudo pip install python-jenkins.

Connecting to Jenkins: import the jenkins module and create a jenkins.Jenkins instance with the server URL, username, and password.

Job operations: server.build_job(job_name) builds a job without parameters;

server.build_job(job_name, {"param1":"value1", "param2":"value2"})

builds a job with parameters.

Additional job actions: server.get_job_info(job_name) retrieves job configuration and build information; server.enable_job(job_name) and server.disable_job(job_name) enable or pause a job; server.copy_job('job', 'job_copy') creates a copy of an existing job.

View operations: server.get_view_config(view_name) obtains view configuration; server.create_view('view4', jenkins.EMPTY_VIEW_CONFIG_XML) creates a new view; server.delete_view(view_name) removes a view; server.view_exists(view_name) checks for view existence.

Other useful functions include retrieving the last build number via server.get_job_info(job)['lastBuild'] and checking if a build is in progress with server.get_build_info(job, build_number)['building'].
